AdvancedTCA® Intelligent Rear Transition Module Base Specification
The objective of this specification is to define hardware platform management aspects of Intelligent (MMC-based) Rear Transition Modules (IRTMs), covering PointTo-Point (P2P) and Clock E-Keying and related hardware platform management topics. This specification defines E-Keying mechanisms without defining specific pinouts or connector descriptions as these may vary from one IRTM to another. Instead, the IRTM implementation specific documentation must define the required pinout mappings to “Ports” as defined in this specification. IRTMs provide electrical and mechanical support for hot swapping. Actual complete implementations for hotswapping of IRTMs require additional levels of support from the Front Board, operating system, and other software.
